The invention discloses low-shrinkage low-viscosity ultrahigh-strength concrete and a preparation method thereof, and relates to the technical field of concrete production. The concrete is prepared from the following components in parts by weight: Portland cement, coarse aggregate, fine aggregate, silica fume, a water reducing agent, fly ash, polypropylene fibers, a lithium silicate and sodium silicate composite aqueous solution, ceramic powder, glass beads and asphalt. The prepared concrete material has ultrahigh strength, especially the compressive strength is greatly improved, the application field is greatly enlarged, the comprehensive performance of concrete can be obviously improved through the synergistic promotion effect of all the components, the fluidity is better, and the pumpability is higher.
本发明公开了一种低收缩低粘度超高强混凝土及其制备方法；涉及混凝土生产技术领域，按重量份计由以下成分制成：硅酸盐水泥、粗骨料、细骨料、硅灰、减水剂、粉煤灰、聚丙烯纤维、硅酸锂与硅酸钠复合水溶液、陶瓷粉、玻璃微珠、沥青；本发明制备的混凝土材料具有超高强度，尤其是抗压强度大幅度提高，应用领域大幅度增加，通过各组分的协同促进作用，能够明显的改善混凝土的综合性能，流动性更好，可泵性更高。
